The outcrop itself shows clear signs of quarrying, particularly to the southwest of the tower, suggesting it served as the primary source of building material for the structure. When the Civil Survey documented the site between 1654 and 1656, they rather bluntly described it as ‘a stumpe of a castle wch was never finished’, noting that one John O’Magher of Clonekeany, identified as an Irish Papist, held ownership of the property.

The tower house rises four storeys high, measuring approximately 12 metres northwest to southeast and nearly 11 metres northeast to southwest, with walls varying in thickness from three quarters to just over a metre. Built from roughly coursed local sandstone rubble with limestone detailing around openings and corners, the structure features a distinctive projecting turret at its eastern angle. The main entrance on the northeast face once boasted what must have been an impressive doorway, though its surround has long since vanished. Above it, however, remains an elaborate wall niche with chamfered edges and a pediment, its curving margins suggesting it once held a coat of arms or foundation inscription, though no trace of such a stone survives today.

Inside, the tower reveals a sophisticated layout despite its unfinished state. A spiral staircase within the projecting turret provided access to all upper floors, each level lit by narrow windows paired with defensive gun loops. The ground floor remains windowless, whilst the upper storeys feature increasingly larger windows; single lights at first floor level expanding to more generous flat headed openings on the second and third floors. The builders incorporated substantial fireplaces throughout: two in the southwest wall serve the first and second floors, the latter featuring a particularly fine four centred arch with chamfered details, whilst the third floor boasts an especially elaborate fireplace in the northeast wall, decorated with a moulded surround and stylised foliage motifs along its lintel, though its curved mantle has partially collapsed over the centuries. The masonry cuts off abruptly above the third floor, leaving this ‘stumpe of a castle’ frozen in time, protected since 1938 under a preservation order.
